InstallatIon

Upon receiving the VWR Hotplate/Stirrer/Hotplate-Stirrer, check to ensure that no damage has occurred in shipment. It is important that any damage that occurred in transport is detected at the time of unpacking. If you do find such damage the carrier must be notified immediately.

After unpacking, place the Hotplate/Stirrer/Hotplate-Stirrer on a level bench or table, away from explosive vapors. Ensure that the surface on which the unit is placed will withstand typical heat produced by the unit and place the unit a minimum of six (6) inches (15.2cm) from vertical surfaces. Always place the unit on a sturdy work surface.

The Hotplate/Stirrer/Hotplate-Stirrer is supplied with a power cord that is inserted into the IEC connector on the back of the unit first, then it can be plugged into a properly grounded outlet. The 120V unit plugs into a 120 volt, 50/60 Hz source. The 230V unit plugs into a 230 volt, 50/60 Hz source. Be sure the power cord is fully and correctly installed into the IEC connector before powering the unit.

Note: 10 x 10, 120V heating models have a fixed power cord terminated with an NEMA 5-15P appliance connector.

MaIntenance & servIcIng

The Hotplate/Stirrer/Hotplate-Stirrer is built for long, trouble-free, dependable service. It needs no user maintenance beyond keeping the surfaces clean. The unit should be given the care normally required for any electrical appliance. Avoid wetting or unnecessary expo-sure to fumes. Spills should be removed promptly after the unit has cooled down. Do not use a cleaning agent or solvent on the front panel or top plate which is abrasive or harmful to plastics, nor one which is flammable. Always ensure the power is disconnected from the unit prior to any cleaning. If the unit ever requires service, contact your VWR representative.

CLEANING CERAMIC TOPS:First remove any burnt-on deposits or spills from the top plate with a scraper (similar to scraping paint off of windowpanes in your home). For your safety, please wear an insulated mitt when using a metal scraper. When the top plate has cooled, apply a few dabs of a non-abrasive cleaner over the surface with a damp paper towel. As a final step, clean with water and wipe surface with a clean, dry paper towel.

CLEANING ALUMINUM TOPS:For simple dust and dirt, clean the aluminum top by using a damp cloth with soap and water. For more stubborn deposits, try using a flat edge wooden spatula to scrape off as much as possible. For more stubborn stains, try using a couple of tablespoons of white vinegar to two pints of water and mix well. Dip a clean cloth into the mixture and gently

MaIntenance & servIcIng (cont’d)

rub the exterior of the aluminum surface. Generally, it is not a good idea to use abrasive pads or cleaners on aluminum, as the metal will scratch easily. If you must use some type of abrasive, try applying baking soda to the surface and then rubbing with a moist cloth. This will work as well as most scouring pads and is less likely to create deep scratches in the surface. Be careful not to use steel wool or scouring pads as they can leave the aluminum riddled with little scratches that make it harder to clean in the future. If you feel you must use steel wool, use the finest grade you can find and use as sparingly as possible with as little pressure as possible. Go with the grain rather than using circular motions.

HeatIng oPeratIng InstrUctIons

The Hotplates and Hotplate-Stirrers have a micro-processor controlled heater that is designed to bring samples to temperature quickly and accurately.

1. Getting ready: a. Turn the heat knob to the off position. Plug power cord into a properly grounded

3-prong outlet. b. Place a vessel with solution and the appropriate accessories in the center of the

top plate. This is important because the vessel should be over the hottest part of the top plate.

2. Setting temperature for Standard Series: a. Turn the heat knob clockwise until the pointer reaches the desired heat setting.

The indicator light above the heat knob will illuminate to indicate the heating feature is in use. The unit will beep 5 (five) times when the set temperature is reached.

b. Temperature adjustments can be made without interrupting heating by turning the indicator knob clockwise to increase heat and counter-clockwise to decrease heat.

c. To stop heating, turn the heat knob to the off position. Your vessel can then be removed.

3. Setting temperature for Advanced Series: a. Turn the heat knob clockwise until the display reaches the desired heat setting.

The display will flash the set-point temperature until the temperature is reached, at which time the display will stop flashing and beep 5 (five) times. When the heat is turned on the indicator light above the heat knob is illuminated. Removing or adding more to a sample content could cause the temperature to fluctuate. If this occurs, the display will again start to flash until the set-point value is stabilized.

b. Temperature adjustments can be made without interrupting heating by turning the heat knob clockwise to increase heat or counter-clockwise to decrease heat.

c. To stop heating, turn the heat knob to the off position. Your vessel can then be removed.

Caution hot top indicator:The caution hot top indicator light warns that the top plate is too hot to touch. The caution hot top indicator light will illuminate when the heat is turned on and remain on until the top plate cools down.

Recall last temperature button:Advanced Series Hotplate/Hotplate-Stirrers have a built-in memory that allows users to recall the last set temperature, even after the unit has been turned off. (The temperature in memory is the last temperature that ran for more than 5 minutes.)

Max Temperature:If the unit has an aluminum top, the max temperature setting is 400°C. If the unit has a ceramic top, the max temperature setting is 500°C.

OPERATING TIPSThe unit may overshoot the temperature up to 10°C before stabilizing at the set-point. The two methods suggested to minimize overshoot are:

1. Metal containers minimize overshoot. CAUTION: When heating metal containers on a ceramic top it is recommended to use the lowest temperature setting possible to limit thermal stress to the ceramic top.

2. If a glass vessel is used, anticipate overshoot. Start with a setting 5-10°C below the desired temperature. When the temperature stabilizes at this lower setting, turn the heat knob to the final temperature. Overshoot is then reduced to about 1°C.

The temperature display on the Advanced units show the actual temperature of the heater not the top plate or sample. The vessel contents being heated may be at a lower temperature depending on the size and insulating qualities of the vessel. It may be beneficial to monitor the temperature of the vessel contents and adjust the set-point temperature accordingly.

This method can be used for calibrating the top plate surface. To set a Single Point Calibration (SPC) adjustment: a. Turn the heat knob clockwise until the display reaches the desired heat setting,

and let the unit stabilize to the user input temperature. The heater temperature has stabilized when the temperature display is no longer blinking and the unit will beep five times.

b. Wait ten minutes for the surface temperature to stabilize. Measure the top plate with a traceable surface temperature measuring device.

c. Press and hold the Last Temperature button. The display will start to scroll through the available SPC options (“UP”, “dn”, “SEt” and “dEL”) as long as the Last Temperature button is held down. Once you select “UP” or “dn” mode and release the Last Temperature button the unit will beep two times and the display will begin to blink quickly. This lets you know you are programming in SPC mode.

NOTE: There is a thirty second time out (Last Temperature button must be pressed at least once in thirty seconds, or unit will exit SPC mode). Do not touch the heat knob while in SPC mode. If the heat knob is adjusted during this procedure you will exit SPC mode.

d. Once the desired option is displayed, release the Last Temperature button. Please see the explanation below for each option.

e. Selecting the “SEt” option saves the Single Point Calibration adjustment for that temperature set point and allows you to exit this SPC mode (see Section c). When the “Set” option is selected “SEt” will be displayed. To save the current SPC point and exit the SPC programming mode, release the Last Temperature button when “SEt” is on the display. The display will now show your set point temperature with a decimal point for that setting.

f. Select the “UP” option if your externally measured temperature of the top plate is higher than the set point on the display. When the “UP” option is selected the current SPC adjusted temperature is displayed and blinking quickly. To increase the SPC, press and release the Last Temperature button multiple

times (do not touch heat knob) until the display reads the value you recorded as the measured temperature of the top plate. Changes are not saved until the “SEt” option is selected (and the Last Temperature button is pressed and released), if the temperature is adjusted too high, delete the SPC adjustment and repeat procedure.

g. Select the “dn” option if your externally measured temperature of the top plate is lower than the set point on the display. When the “dn” option is selected the current SPC adjusted temperature will be displayed and blinking quickly. To decrease the SPC, press and release the Last Temperature button multiple times (do not touch the heat knob) until the display reads the value you recorded as the measured temperature of the top plate. Changes are not saved until the “SEt” option is selected (and the Last Temperature button is pressed and released), if the temperature is adjusted too low, delete the SPC adjustment and repeat procedure.

h. Selecting the “dEL” option will delete all Single Point Calibration points and allow you to exit this SPC mode (see Section c). When the “dEL” option is selected “dEL” will be displayed. To delete all SPC points and exit the SPC mode release the Last Temperature button when “dEL” is on the display.

i. For set point temperatures with a SPC adjustment, there will be a decimal point in the display. Once the SPC adjustment is set, the display will blink while the unit’s temperature is settling. When the SPC set point is reached, the display will stop blinking and the unit will beep five times.

j. This process may be repeated for up to three separate set points. If a fourth SPC set point is entered, the first set point will be overwritten. To readjust an existing SPC set point, you must delete the current settings (all SPC points will be deleted, and the decimal points will no longer be displayed at those temperatures) and repeat the SPC procedure. If SPC adjustments are not deleted prior to resetting SPC for a set point then the temperature adjustment will not be accurate

k. The SPC adjustments are limited to the maximum and minimum temperatures and limits allowed by the particular unit.

The micro-processor controlled ramping feature slowly increases speed until the set-point is reached. This feature helps to avoid splashing, improves magnetic coupling and provides excellent low end control. The micro-processor also monitors and regulates the stirring speed, sensing your requirements whether you’re stirring an aqueous, viscous or semi-solid solution.

Initial stirring speed may exceed set speed if the following conditions exist:

1. The stirrer is set at a low speed and the stirrer has not been operated for a extended period of time.

2. The stirrer is set at a low speed and it is the stirrer’s initial use.

1. Getting ready: a. Turn stir knob to the off position. Plug power cord into a properly grounded

outlet. b. Place a vessel with solution and the appropriate spin bar in the center of the top

plate.

2. Setting speed: a. Turn the stir knob clockwise until the pointer reaches the desired speed setting.

The stir indicator light above the stir knob will illuminate to indicate the stirring feature is in use. The stir indicator light will blink while reaching the set-point. Once the set-point is reached the light will remain lit.

b. Speed adjustments can be made without interrupting stirring by turning the stir knob clockwise to increase speed, or counter-clockwise to decrease speed.

c. To stop stirring, turn the stir knob to the off position. Your vessel can then be removed.

Stir protection for Hotplate-Stirrers: If stirrer motor stops or fails, the unit will automatically shut down the heater.

oPeratIng tIPsThe stirrer increases speed at a steady rate until the set-point is reached, if the stir bar is too large or the liquid is too viscous, the stirrer may not reach its set-point. The set-point speed needs to be reduced. The magnetic strength of stir bars reduce over time and may need to be replaced.

Stirring vessels in oil baths: When heating and stirring a reaction vessel within an oil bath or similar set-up, the

stirring function will stir up to approximately one (1) inch (2.54cm) from the top plate. The stirring speed will vary according to liquid viscosity, stir bar length and distance from the top plate. Adjust one or all of these to achieve the desired stirring speed.

EXAMPLE: The closer the reaction vessel is to the top plate the stronger the magnetic connection.
